In a separate study, [1]} resolved the Fe K\(\alpha \)  line region in Cyg X-1 through spectral analysis. The Chandra X-ray observatory detected the source in an intermediate spectral state during these observations. The authors observed a narrow line around 6.42 keV along with a broad line feature at \(\sim \)  5.82 keV and a smeared edge at 7.3 keV. These results support our findings, as the study reported a photon index around 1.8 which is close to the value we found during E1. The value of R\(_{in}\)  reported in that study is similar to the value of R\(_{in}\)  found during E1 in this work. Two different lines and a smeared edge are not observed in our study, either because of the superior spectral resolution of Chandra in comparison to NuSTAR [2]}, [3]}, or because they may not be present in GRS 1716–249.
